Patented Aug. 8, 1939 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to a combination windshield and window-cleaner andhas for its object to provide a combined wind-shield and window-cleanerwhich will be simple in construction, cheap to manufacture, efficient inits working, and exceedingly durable.

My invention consists of certain novel features and details ofconstruction, as will be more fully described hereinafter and finallypointed out in the claim.

With these objects in view I will now describe my invention referencebeing had to the accompanying drawing in which similar letters ofreference indicate corresponding parts, and in which Figure l is a frontelevation partly in perspective of my improved wind-shield cleaner as itappears completely assembled.

Fig. 10 is an end elevation of the windowcleaner shown in Fig. 7.

Fig. 11 is a side elevation of the wind-shield cleaner, showing the bossfor connecting the cleaner proper to the operating arm or lever from thevacuum cylinder or electric operating device, and

Fig. 12 is a transverse sectional view of the same, taken on line 33 ofFig. 11.

A detailed description of my invention is as follows: i

A represents the case of the wind-shield and window-cleaner, which issemi-circular in form and is provided with flanges B, on both open edgesand is enclosed at both ends C, each of which is provided with holes,into which is mounted the revolving blades D. These blades are cast ormoulded from rubber upon a core of wire E, which runs through the entirelength of the blades D, and project a suitable distance beyond each endthereof, and are threaded, the purpose of which will appear hereinafter.

The revolving blades D are formed in the shape of corrugations out ofone piece of rubber and are so arranged, that at least two of theseblades come into contact with the glass at the same time, thuspresenting a definite cleaning sur face for removing rain and snow fromthe windshield or window-glass.

The revolving blades D are mounted in the case A, at each end thereof,and are held in a rigid position by means of thumbnuts F. When it isdesired to change the position of the blades, the thumb-nuts areloosened and the blades revolved or moved to a different position. Thisonly becomes necessary when the blades in contact with the glass becomeworn.

A boss G is formed on or secured to the back of the case A, and isprovided with a hole H, for connecting the cleaner proper to theoperating arm or lever I, of the vacuum cylinder or other operatingdevice.

A tongue J is cut from the back of the case A, and adapted to be bentinto such position as to embrace the operating arm or lever, the purposeof which is to steady the cleaner when working, thus preventing awiggling motion on the glass. This tongue J is best shown in Figs. 10and 11.

In the modified form of revolving blades, I have shown one of the rubberblades removed and a strip of felt K, inserted in its stead, the purposeof which is for absorbing and containing an antifreeze solution, toprevent ice forming on the Wind-shield.

On the shaft L, which runs from the vacuum cylinder or other operatingdevice, I have provided a spring M, having a hub N, which fits over theend of said shaft and through which the operating arm or lever passesand is held in position on said shaft L, by any suitable and convenientmeans, preferably by a cotter-pin, (not shown). The lower portions ofthe spring M, is broadened out as best shown at 0, Fig. 8, and isadapted to engage the operating arm or lever for the purpose of exertingtension on said arm or lever, which in turn holds the cleaner morefirmly against the glass.

In the modified form of cleaner shown in Figs. 7, and 9, I have shownthe case of the cleaner provided with a socket P, into which is securedan ordinary handle Q. This form of cleaner is intended for use incleaning windows. The handle and socket being the only innovation fromthe wind-shield cleaner as shown in the several other figures of thedrawing.

Having described my invention, what I claim and desire to secure byLetters Patent is:

A window cleaner, consisting of an elongated semi-circular case intowhich is journalled a shaft upon which is mounted a rubber wiper bodyhaving a plurality of wiping edges integral therewith and disposedlongitudinally of and spaced about the periphery thereof, means to holdsaid shaft in a rigid position within the case, and means connected tothe case for moving same over a surface to be wiped, all substantiallyas shown and described.
